Vox AC15CC1 preset

Close · 76/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The AC15CC1 Custom Classic is a 15-watt Class A combo with two cathode-biased EL84s. On this drawing a single input feeds an ECC83 stage with a Top Boost Volume and a Treble and Bass stack; op-amps drive and recover the spring reverb under a Reverb Mix control. A MOSFET phase-shift oscillator gives tremolo (Speed, Depth), a Master Volume follows, and a second ECC83 is the long-tailed-pair phase inverter. Solid-state rectified.
